Three Advantages of Dual extrusion 3D Printers

Support Structures: Virtually, the capacity of a dual extruder to print supports using soluble filaments is its most significant benefit. Support structures are necessary for some intricate models with overhanging elements to prevent deformation during printing. Supports are printed using the same filament as the model when using a single extruder, and they are subsequently removed at the risk of breaking the item. Additionally, interior supports that some models require are impossible to remove after a part has been printed. This issue can be resolved by printing supports with a soluble filament using the second extruder.
Multi-colour Printing: With the simultaneous use of two filaments made possible by dual extruder 3D printers, dual-color items can be produced without switching filaments.
Accelerated pace: Compared to single extrusion 3D printing, two extruders speed up the process. Making two identical components at once in the mirror or duplication modes will allow you to double the production volume of your 3D printer if it has a dual-independent extruder.
Reduced downtime: It is unnecessary to stop printing if one extrusion becomes clogged immediately; instead, you can continue using the second extruder, reducing downtime and boosting printing efficiency.
